Find the discriminant and the numbers of real roots for this equation: 4x^2+12x+9=0
Len [333]

Answer:

D=0

The quadratic equation has one real root with a multiplicity of 2.

Step-by-step explanation:

Given a quadratic equation:

 ax^2+bx+c=0

You can find the Discriminant with this formula:

D=b^2-4ac

<em> </em>In this case you have the following quadratic equation:

4x^2+12x+9=0

Where:

a=4\\b=12\\c=9

Therefore, when you substitute these values into the formula, you get that the discriminant is this:

D=(12)^2-4(4)(9)\\\\D=0

Since D=0, the quadratic equation has one real root with a multiplicity of 2 .
